// considered, but was secondary. (refer to Onyx QA Entry #4920)

// algorithm.  Lowering the ratio will lower rapidity and improve space
// efficiency. This effect will be most noticable when working with
// containers of few elements (few being less than 32 for the general case)
// If your use case is with containers that typically have many elements
// lowering the ratio will have less effect on rapidity.
//
// The minimum elements parameter refers to minimum amount of additional
// capcity requested (in number of elements) when more memory is needed.
// Rapidity with containers of few elements will be affected most noticably
// as this amount this is lowered.
//
// For strings, the specializations on char and wchar_t were seen as an
// exploitable common case, and have their own more specialized template
// function overloads in the string header.  These are tweakable here
// with the STRING version of these macros.
